Bloggers, be warned! You can adopt all the pseudonyms you want — but armed with this nifty Web app, readers will still be able to figure out your gender.

Judging by our own initial research, the GenderAnalyzer really almost sort of works. Kate Hopkins (of the food blog Accidental Hedonism) was correctly labeled a lady. Markos Moulitsas and James Wolcott will be relieved to learn that they’re as masculine as masculine gets. But something hinky occurred when we put Ann Coulter and Katie Couric through the wringer: According to GenderAnalyzer, they’re no ladies.
